Debian Security Advisory

DSA-986-1 gnutls11 -- buffer overflows

Date Reported:

06 Mar 2006

Affected Packages:

gnutls11

Vulnerable:

Yes

Security database references:

In the Bugtraq database (at SecurityFocus): BugTraq ID 16568.
In Mitre's CVE dictionary: CVE-2006-0645.

More information:

Evgeny Legerov discovered several out-of-bounds memory accesses in the DER decoding component of the Tiny ASN.1 Library, which is also present and used in GnuTLS, the GNU implementation for Transport Layer Security (TLS) 1.0 and Secure Sockets Layer (SSL) 3.0 protocols and which allows attackers to crash the DER decoder and possibly execute arbitrary code.

The old stable distribution (woody) is not affected by these problems.

For the stable distribution (sarge) these problems have been fixed in version 1.0.16-13.2.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your gnutls packages.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
